Italian Grand Prix – The Williams duo of Felipe Massa and Lance Stroll topped the 16-minute-long free practice three session, which was subjected to heavy rain.
The continuing rain – which had already hampered the schedules of the support races – meant no running was permitted for the majority of the session, with only the safety car venturing out to test the conditions.
The session started with 16 minutes of the hour remaining, with all drivers heading out for at least one exploratory lap of the saturated Monza circuit.
The Toro Rosso pairing of Carlos Sainz and Daniil Kvyat were the first drivers to try ‘flying’ laps, with Sainz setting the early pace with a 1:41.515.
Renault’s Nico Hulkenberg beat the benchmark by two hundredths of a second, before both Williams drivers went to the top of the timing sheets.
Felipe Massa set the pace with a 1:40.660, one quarter of a second faster than his rookie team-mate Lance Stroll.
Jolyon Palmer (Renault) and Marcus Ericsson (Sauber) were the only other drivers to complete timed laps, with the rest of the field electing to complete minimal running.
